  • Annulment of bacterial antagonism improves plant beneficial activity of a Bacillus velezensis consortium [Elektronski vir]
    Shao, Jiahui ...
    Bacillus sp. strains that are beneficial to plants are widely used in commercial biofertilizers and biocontrol agents for sustainable agriculture. Generally, functional Bacillus strains are applied ... as single-strain communities since the principles of synthetic microbial consortia constructed with Bacillus strains remain largely unclear. Here, we demonstrated that the mutual compatibility directly affects the survival and function of two-member consortia composed of Bacillus velezensis SQR9 and FZB42 in the rhizosphere. A mutation in the global regulator Spo0A of SQR9 markedly reduced the boundary phenotype (appearance of a visible boundary line at the meeting point of two swarms) with wild-type FZB42, and the combined use of the SQR9(△spo0A) mutant and FZB42 improved biofilm formation, root colonization, and the production of secondary metabolites that are beneficial to plants. Furthermore, alleviation of antagonistic interactions of two-member Bacillus consortia improved its beneficial effects to cucumber in a greenhouse experiment. Our results provide evidence that social interactions among bacteria could be an influencing factor for achieving a desired community-level function.
